Cold-rolled ribbed steel structure design points: fatigue stress amplitude limit. Steel plate for class members under fatigue loads, when checking the maximum stress fatigue does not exceed 300N / ram2, fatigue stress ratio is not greater than 0.3, the fatigue stress amplitude reinforcement should not exceed 120N / ram2. Concrete strength selection. For reinforced concrete structures in a class environment wholesale 10mm cold-rolled steel wire rod, its concrete strength not less than C20. Cold-rolled ribbed steel structure design points: The minimum reinforcement ratio selection. The use of reinforced concrete structures under flexural members minimum longitudinal reinforcement ratio pull cold-rolled steel wire rod 10mm rebar spot, take O. 2% and 45ft / fy%, whichever is greater of 10mm cold-rolled steel wire rod price, when using C35 concrete after the entry of 0.196%. In other words, when the concrete strength class C35 and below. The minimum reinforcement ratio is from 0.2% to control, not blind other strong substitution reinforcement. 10mm cold-rolled steel wire rod manufacturers _ _ cold-rolled steel wire rod cold-Ding Ding Ding Ding Industrial Co., Ltd., Henan Province by.
